Having only 55k on your 01 is awesome, but seals will still wear over time, not just use. Did you mention what oil weight you use?

I use the recommended oil. I am going to have it checked out by a friend who works at a BMW dealerership and hopefully it is just the tensioner as Justin said.
Thanks for the advice.
